MAGAZINE FOR HEATING-STOVES.

SPECIFICATION forming part of Letters Patent No, 727,459, dated May 5, 1903.

Application filed April 24,1901. I

To (LZZ whmn it may concern:

Be it known that I, EMIL SCHOUP, a citizen which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to improvements in magazines for heating stoves or furnaces in which coal is used for fuel.

My present invention consists of an improved magazine ofproper dimensions to fit within a suitable stove-shell; and it consists of two upright cylinders in concentric arrangement and separated throughout their length by an annular air-chamber, which is open at its lower end and is provided at its closed upper end with a series of draft-openings, the interior of themagazine-chamber being connected to the said air-chamber by means of a series of longitudinal slots in the inner cylinder, whereby the smoke and gases of the magazine-chamber are carried downward with the draft to the fire-pot.

The object of my present invention is to provide an upright magazine for heating stoves and furnaces having an annular downdraft air-chamber opening at its lower end into the fire-pot and connected with the interior of the magazine by proper draft-openings for the purpose of conducting the smoke and noxious gases generated in the magazine downward to the fire-pot, thereby preventing their escape into the living-rooms and also socuring a substantial saving of fuel.

The novel feature of my present invention resides in the means for conducting the noxious gases of the magazine-chamber downward to the flame.

In the accompanying drawings similar reference-numerals indicate like parts throughout the several views, in which- Figure 1 is a view in elevation of a common form of heating-stove containing my improvement, broken away in part to show the relative arrangement of means for securing a Serial No. 67,192. (No model.)

downdraft from the magazine. Fig. 2 is a plan view of Fig. 1, broken away in part to show the annular air-chamber. Fig. 3 is a detail plan of the ring damper for closing the natural-draft openings to the annular airchamber. Fig. 4 is a detail perspective of the inner cylinder which forms the magazinechamber.

My improvement is adapted to be mounted in any suitable form of heating-stove 1, having a proper stove-shell 2 and a proper fire-pot 3 arranged therein. In this containing-shell 2 is removably mounted my improved downdraftmagazine, which is constructed and arranged as follows: Anouteruprightcylinder4,open at both ends and tapering downwardly, as shown, has its walls gradually thickened at its lower end to better resist the heat from the fire-pot and has its upper end provided with diametric lateral apertured ears 9, by which it is suspended from the top of the stove 1 by means of proper bolts 5 or other proper manner, leaving an annular space 6 between the said cylinder 4 and the walls of the containing-shell 2. Within this cylinder 4 and in concentric relation therewith is arranged the upright inner cylinder 7, of substantially equal length as its containing-cylinder 4, and provided upon its upper end with an outer peripheral flange 8, of proper width to rest on the upper end of the said cylinder 4 and securely close the space between the upper ends of the said cylinders. This flange 8 has a pair of apertured peripheral ears 10, adapted to register with the said ears 9 and to receive the same securing-bolts 5, Fig. 1, and has a series of small draft-openings 12. This inner cylinder 7 tapers downwardly, has its walls thickened toward the lower end, and is so arranged within the said containing-cylinder 4 as to leave an annular air-chamber 11, opening at its lower end into the fire-pot and closed at its upper end by the said flange 8, except for the openings 12. This annular air chamber is preferably of equal width throughout its length and is provided with a downdraft by means of the said inlet-openings 12 in the manner about to be described. This inner cylinder 7 is provided with a series of peripheral slots 13 of proper width, preferably eight in number, and extending nearly to the ends thereof, as shown, thereby connecting the interior chamber of the magazinewith the said annular air-chamber '11. The peripheral slots 13 are too narrow to admit any fuel and yet are of sufficient width to freely admit the gases of the magazine to the said airchamber 11, after which they are promptly carried down ward to the combustion-chamber by the natural draft.

My improved magazine is surmounted by a fixed top l4,'having a series of vertical draftopenings 15 in register with the said openings 12 of the flange 8, respectively. In a proper annular recess in the top 14 is rotatably mounted an annular damper-plate 16, havinga series of vertical openings 17,adapted to register with the said draft-openings 12 and 15 when desired. These draft-openings are of any'proper size to establish a suitable natural draft.

The operation and manner of employing my invention is obvious from the above description, and, briefly stated, is as follows: When my invention is used, the only draft to the combustion -chamber is downward through the said draft-openings 12, 15, and 17 and the air-chamber 11, which is sufficient for a perfect combustion. When this downdraft is established, the resulting downward suction will continuously draw from the steaming fuel of the magazine all the smoke, gases, and noxious fumes generated therein and carry the same downward to the fire-pot, where they are consumed. This downdraft can of course be regulated or entirely shut off by means of the damper-plate 16.

A large saving of fuel is effected by the use of my improved downdraft-magazine, which is equally applicable to furnaces.

What I desire to secure by Letters Patent 1s- 1. In a stove,the combination with the shell thereof, a fire-box arranged therebeneath, and a top surmounting said shell, of a magazine arranged in said shell and opening into said fire-box, said magazine comprising inner and outer concentric cylinders spaced from each other to form an intermediate air-chamber, the inner cylinder having at its upper end an outwardly-extending flange provided with diametrically opposite outwardly-extending ears, said flange closing the upper end of said air-chamber but provided with draft-openings for feeding air thereto, the upper end of the outer cylinder resting against said flange and provided with diametrically opposite outwardly-extending ears arranged in coincident relation to the ears of the inner cylinder, and means for connecting said ears to the top-for suspending the magazine therefrom.

2. In a stove,the combination with the shell thereof, a fire-box arranged therebeneath, and a top surmounting said shell, of a magazine arranged in said shell and opening into said fire-box, said magazine comprising inner and outer concentric cylinders spaced from each other to form an intermediate air-chamber, the inner cylinder having at its upper end an outwardly-extending flange provided with diametrically opposite outwardly-extending ears, said flange closing the upper end of said air-chamber but provided with draft-openings for feeding air thereto, the upper end of the outer cylinder resting against said flange and provided with diametrically opposite outwardl y-extendin g ears arranged in coincident relation to the ears of the inner cylinder, means for connecting said ears to the-top for suspending the magazine therefrom, and a damper-plate adjustably mounted upon the top and provided with a series of draft-openings adapted to register with the openings of the flange of the inner cylinder for controlling the flow of air therethrough.

Signed by me at Lima, Allen county, State of Ohio, this 20th day of April, 1901.

EMIL SOI-IOUP.
